Contamination assessment and remediation at the Hobart Tasmania railyards
In 1996 the Australian Commonwealth Government (Australian National Rail - ANR) engaged consultants Sinclair Knight Merz (SKM) to undertake contamination assessment and (where necessary) remedial works at over 70 rail sites in Tasmania, South Australia and Victoria. As part the overall assessment program, significant contamination assessment studies and remediation works were undertaken by SKM at the former ANR Hobart rail site in Hobart, Tasmania, Australia. The assessment and remediation works spanned 5 years and included works to gather sufficient evidence regarding the significance and likely behaviour of a variety of contamination sources at the site. This information was then used as a basis for making informed decisions in relation to environmental management, regulatory compliance and site divestment. Intrusive and engineered remedial works undertaken across targeted areas of the site during the contract included the removal of contaminated soils and groundwater. Quantitative health Risk Assessment (QRA) works were also undertaken to support remedial activities and to determine potential impacts on site workers and the receiving Derwent River aquatic environment. The remedial solutions were customised to allow for a balanced approach that accepted that some rail operations can necessarily require environmental management, while recognising that rail activities would continue. The outcome of the assessment and remedial works resulted in acceptance and site sign-off from the Tasmanian State Environmental Regulator and the successful transfer of the property ownership and environmental liability from ANR to the State.
